THREE DIMENSIONAL SOY PROTEIN-CONTAINING SCAFFOLDS AND METHODS FOR THEIR USE AND PRODUCTION

摘要

Porous soy protein-based scaffolds and methods for making the scaffolds using 3D printing techniques are provided. Also provided are tissue growth scaffolds comprising the porous soy protein-based scaffolds and methods for growing tissue on the tissue growth scaffolds. The porous soy protein-containing scaffold comprises a plurality of layers configured in a vertical stack, each layer comprising a plurality of strands comprising denatured soy proteins.

主权项

1. A method of forming a porous biopolymer-containing scaffold, the method comprising:
extruding a slurry comprising a biopolymer in the form of a first layer, the first layer comprising a plurality of strands; and extruding the slurry in the form of one or more additional layers, each additional layer being vertically stacked upon the previously extruded layer and comprising a plurality of strands, wherein the mass flow rate of the slurry is maintained at a substantially constant rate during extrusion by adjusting one or both of the extrusion pressure and extrusion speed during extrusion.
